Witnesses told police the two cars were speeding in adjacent lanes and appeared to be racing. Twenty-year-old Shauna Julian-Trombley, of North Grosvenordale, lost control of her vehicle when the other car abruptly entered her lane. The car struck a wire rope guardrail, entered the median and went up an embankment.

The vehicle rolled over, and Julian-Trombley was ejected. She was pronounced dead at the scene.

A passenger, 17-year-old Kerissa Marquis, of Thompson, was treated for minor injuries.
